Description

Technical Field

[0001] The utility model relates to the technical field of reclaimed rubber production, in particular to a rubber material sorting device. Background Art

[0002] With the gradual improvement of people's living standards and the rapid development of the logistics industry, the number of private cars and trucks in my country has increased year by year. The increase in the number of vehicles has driven economic development. At the same time, the consumption and wear of automobile tires have also generated a lot of garbage - waste tires. Waste tires are common solid waste pollutants. People recycle them through many ways to achieve harmless treatment. The existing treatment methods include preparing rubber powder, recycled rubber, fuel oil, etc. There are many types of existing waste tires, and the brands are heavy. Their tire widths and materials are inconsistent. Therefore, when processing the rubber materials of waste tires, they need to be sorted first.

[0003] The existing technology mostly adopts manual sorting, which has low overall efficiency and high labor intensity; metal foreign objects embedded in the tires during sorting can easily scratch the sorting personnel, causing safety hazards; manual classification and placement of tires of different brands after sorting takes up a large area, and sorting by different people can easily cause mixed classifications;. Utility Model Content

[0004] Therefore, the technical problem to be solved by the utility model is to overcome the defect of inconvenient sorting in the prior art, thereby providing a rubber sorting device.

[0005] The above technical objectives of the utility model are achieved through the following technical solutions:

[0006] A rubber material sorting device comprises a support and a plurality of continuously arranged conveyor belt devices, wherein the conveyor belt device is arranged on the support, and is characterized in that it also comprises a magnetic separation device, a rejecting device and a classification device which are arranged in sequence, wherein the magnetic separation device, the rejecting device and the classification device are all arranged on the support and located above the conveyor belt device, wherein the rejecting device comprises a rejecting frame, a rejecting plate, two rejecting transmissions and a rejecting drive, wherein the rejecting frame is fixed above the support, wherein the rejecting plate is connected to the two rejecting transmissions and is controlled by the rejecting drive, wherein the rejecting drive is arranged on the rejecting frame, wherein the classification device comprises a classification frame, a plurality of classification push plates, a classification transmission and a classification drive, wherein the classification frame is fixed on the support, wherein the classification push plate is connected to the classification transmission and is controlled by the classification drive, and wherein the classification drive is arranged in the classification frame.

[0007] By adopting the above technical solution, the waste tires are first placed on the conveyor device for transportation, and then passed through the magnetic separation device for magnetic separation operation. The waste tires with metal foreign matter are removed by the removal device, and the waste tires without metal foreign matter continue to be transported. After that, the waste tires pass through the classification device and are classified and piled according to the different brand marks on the waste tires, thereby achieving the purpose of sorting and classification. The present application has a simple structure and is easy to use. The setting of the removal device and the classification device can avoid manual operation, avoid metal foreign matter scratching workers and reduce dust pollution caused by waste tires. The automatic operation of the classification device can automatically summarize and organize, reduce the intensity of manual labor and greatly improve work efficiency, which is conducive to improving production efficiency.

[0008] Furthermore, a limit plate is provided on the side of the magnetic separation device away from the rejection device, and the limit plate is relatively arranged on both sides of the width direction of the bracket and is arranged on the conveyor belt device; the magnetic separation device is connected to the rejection device signal control, the rejection transmission is a chain transmission and is arranged at both ends of the rejection plate, the rejection drive is connected to one of the rejection transmissions and controls its rotation, the rejection plate is arranged along the length direction of the conveyor belt device and its two ends are fixed on the two rejection transmissions, and a processing frame is also arranged at the bottom of one side of the rejection frame, and the processing frame is arranged on the side of the bracket.

[0009] By adopting the above technical solution, two relatively arranged limit plates limit the waste tires in the middle of the conveyor belt, thereby ensuring that the tires can be fully scanned by the magnetic separation device and ensuring the accuracy of the subsequent rejection device operation; the rejection drive controls the rejection transmission to drive the rejection plate to move to sweep away the waste tires with metal foreign matter and stack them in the processing frame, which is convenient for transfer and removal of metal foreign matter.

[0010] Furthermore, the classification transmission includes two rotating shafts arranged parallel to each other, and each rotating shaft is provided with rotating teeth coaxial therewith at both ends. The two rotating teeth located on the same side of the two rotating shafts are transmitted through a classification chain. The two ends of the classification push plate are respectively fixed on the classification chains at both ends. The classification push plate is arranged along the length direction of the conveyor belt device and is arranged in an array on the classification chain. The classification push plate is also parallel to the rotating shaft.

[0011] Furthermore, one of the rotating teeth is also connected to a classification drive for controlling its rotation, and the classification drive is a rotating motor and is vertically fixed in the classification frame. The rotating tooth and the classification drive are connected through a classification gear set, and the classification gear set includes a first classification gear and a second classification gear that are meshed with each other. The first classification gear is coaxially arranged with the rotating tooth, and the second classification gear is coaxially arranged with the output shaft of the classification drive. The axes of the first classification gear and the second classification gear are perpendicular and both are bevel gears.

[0012] By adopting the above technical scheme, the classification drive rotation drives the first classification gear to rotate. Since the first classification gear and the second classification gear are mutually meshing bevel gears, the vertical positioning rotation is converted into the horizontal positioning rotation. The second classification gear rotation drives the meshing teeth to rotate, so that the classification chain mounted on the meshing teeth rolls, and the classification chain drives the classification push plate to move. When the classification drive rotates forward, it drives the classification push plate to move clockwise, and the classification push plate can push the waste tire above the conveyor belt device to the side close to the control console and fall into the receiving frame. Otherwise, the classification push plate moves counterclockwise, and the classification push plate pushes the waste tire to the side away from the control console.

[0013] Furthermore, support frames are extended on both sides of the classification frame corresponding to the classification chains, and the support frames are arranged along the length direction of the classification chain. Two reinforcing rods parallel to the rotating axis are also arranged in the classification frame, and a plurality of weight-reducing holes are arranged on the classification push plate.

[0014] By adopting the above technical scheme, the support frame is used to fix the classification chain to ensure smooth movement on the upper and lower sides, and to prevent the classification chain from falling under the action of gravity. Soft lubricating parts can be arranged inside the support frame to increase the lubrication of the classification chain and improve the smoothness of the chain transmission; the reinforcing rod increases the structural strength of the classification frame; the weight-reducing holes on the classification push plate are used to reduce the weight of the classification push plate to prevent it from falling off the rotating shaft, thereby ensuring the safety of the classification movement.

[0015] Furthermore, export plates are extended outward on both opposite sides of the bracket, and the export plates are correspondingly arranged below the side of the classification rack. The height of the export plate close to the bracket is higher than the height of the export plate away from the bracket. A material receiving frame is arranged below the side of the export plate away from the bracket.

[0016] By adopting the above technical solution, the lead-out plate guides the waste tires to smoothly move downward along the movement of the classification push plate into the corresponding receiving frame, thereby realizing the classification operation of tires of different brands and miscellaneous brands; among them, the receiving frame at the end of the conveyor belt device is the main receiving place, which is directly transferred for cleaning and cutting operations. The waste tires in the receiving frames on both sides of the conveyor belt device will be stored for subsequent use.

[0017] Furthermore, a control console is provided between the rejection device and the classification device. The control console is provided on the side of the bracket. The control console is connected to the classification device by signal control. The control console includes a camera and a plurality of control switches. The camera is extended above the conveyor belt device.

[0018] By adopting the above technical solution, the camera captures and records the brand mark on the waste tire, and can control the waste tire to enter the corresponding receiving frame through manual identification or automatic identification by connecting to the control center program. During manual identification, the corresponding control switch is manually operated to rotate the classification drive motor forward, reverse or not operate, so that the waste tire moves to the left or right or continues to move backward and falls into different material classification frames to realize the classification operation; the program automatic control can perform image comparison according to the pre-set situation, and then make the corresponding waste tire fall into the corresponding receiving frame, thereby reducing the labor intensity of manual labor.

[0019] Furthermore, a loading structure and a unloading structure are respectively provided on both ends of the bracket, the loading structure is a conveyor belt structure and is obliquely arranged on the bracket, the height of the loading structure close to the magnetic separation device is higher than the height of the loading structure away from the magnetic separation device, the unloading structure is also a conveyor belt structure and is obliquely arranged on the bracket, the height of the unloading structure close to the classification device is lower than the height of the unloading structure away from the classification device, and a receiving frame is also provided on the end of the unloading structure away from the classification device.

[0020] By adopting the above technical scheme, the left side of the loading structure is lower than the right side, which is convenient for carrying and dumping, and can also reduce the labor intensity during manual handling; the left side of the unloading structure is lower than the right side, so that the waste tires can fall from a higher place. Due to the elastic effect of the waste tires themselves, they can bounce when falling into the receiving frame, thereby shaking off some dust or stones and debris adhering to the waste tires, thereby facilitating subsequent cleaning and cutting operations; raising the end of the unloading structure can make the volume of the receiving frame below the unloading structure larger, so that more waste tires can be transported after being accumulated.

[0021] In summary, the technical solution of the utility model has the following advantages:

[0038] like Figure 1 and Figure 3 As shown, a control console 6 is also provided between the rejecting device 4 and the classification device 5. The control console 6 is provided on the side of the bracket 1. The control console 6 is connected to the classification device 5 by signal control. The control console 6 includes a camera 61 and a plurality of control switches 62. The camera 61 is extended and provided above the conveyor belt device 2. The camera 61 photographs and records the brand mark on the waste tire. The waste tire can be controlled to enter the corresponding receiving frame 13 by manual identification or automatic identification by connecting to the control center program. During manual identification, the corresponding control switch 62 is manually operated to rotate the motor of the classification drive 54 forward, reverse or not operate, so that the waste tire moves to the left or right or continues to move backward and falls into different receiving frames 13 to realize the classification operation.
